The search engine can have some improvement, but when I search for 'epub3 video' around the third hit give a code example how to do it. No rocket science involved there.
For some searches the more advanced version needs to be used.

If I had a well-behaved ePub 3 reader, I'd be creating ePub 3 books already.

I doubt HTML5 is simpler then XHTML. Also, the ePub3 ToC is more difficult then the NCX ToC. Overall, ePub3 (IMHO) ePub3 is not easier then ePub. Plus, there are not many tools to help with ePub3. And given that there are no real readers for ePub3, making eBooks now in ePub3 is a total waste of time and effort as nobody will be reading them.

I would say simpler to understand but more difficult to code. HTML5 uses semantics and groupings with semantic boundaries which could easily make it more difficult initially but more powerful. IMHO it is more readable since it discourages the incessant use of <div> all over the place which makes understand much more difficult.

I do think the ePub3 TOC method is superior to the ePub2 version. For one thing it is pure html instead of a different standard of ncx format. It is more powerful in that you user can control how far down the TOC levels should descend and it is solves the problem of inline TOC verse external TOC since the same file can be used for both. Unfortunately the ncx debacle will still be with us to support ePub2 readers for a while.

I challenge the word "discourage". I think the most appropriate wording is "it offers a systematically-established semantic-oriented way of replacing the <div>'s".

In other words: HTML5 offers uniform, very detailed tags to mark the semantics of your document, even though it does not disallow "bad (i.e., non-semantic) usage" of generic elements like <div>.
